I decided to just go ahead and build an IDF early Markava as it would have appeared in June of 1982 during its baptism of fire in Lebanon. The kit being used for this build is Italeri’s 72nd scale Merkava I kit No. 7005 released back in 2002. This kit was originally released by ESCI as kit No. 8323. Date of original release is unknown to me. Donor parts from the Revell Merkava III kit No. 03134 will be used to update some of the original parts were needed on this build. For such an old kit it is very well detailed. Anyhow, I got this one started more than a month ago to join in on the fun over at Missing-Lynx’s Braille forums weekly update and to enjoy my favorite flavor - 72nd scale armor.
I already have two unfinished Braille build logs started here on this forum and I will be getting back to them as time permits. I’m also currently involved in a 35th scale campaign build but I just couldn’t keep myself from putting together one of my most favorite of tanks. I would like to share this build with all of you so here’s what I’ve gotten done so far.

Got the lower hull together without any issues other than to fill in the seams up at the lower front plate and drilled out three holes on each gear drive housing where it mates to the lower hull (this feature shown below). The upper hull is just sitting on top of the lower hull for the photographs, not ready to cement them together yet. I had to use a small piece of styrene on the exhaust shroud because it was too short in length (indicated with red arrow). Cleaned up the recessed panel lines and drilled out the lifting hooks on the rear deck (circled in red).

Replaced the molded on grab handles with brass rod and used super glue to fill the seam between the rear plate and upper hull (you could just see a small gap at the left rear corner – super glue becomes transparent when sanded and polished). Fitted the rear side stowage boxes to the upper hull.

Removed the molded on secured tools I plan on replacing this feature with the secured tools from the Revell Merkava III kit. Engraved the left side rear hatch opening where the molded on secured tools resided. Added mud flap securing straps to both sides where indicated on the photograph.

Enclosed the exhaust shroud opening at the rear with a piece of black painted sheet styrene. Fabricated two exhaust pipes from both brass and styrene rod.

Drilled out the lightening holes on the drive wheels, I know that these sprockets have at least four holes in each of them but the exact shape of these holes escapes me and they are not correct, but its better than not having them. I later attached the drive wheels to a Dremel rotary tool and with both a round and half round file I reshaped the inside surfaces and thinned down the side surfaces of the sprocket teeth to better represent the these surfaces as on the real vehicle.
The kit road wheels come as a single solid wheel and the rims are deeper than those used on the real vehicle so I replaced them with the Revell Merkava IIIs road wheels, unfortunately there are only enough of these road wheels in Revell’s kit to make 10 pairs, the other two sets come as spider wheels and these were not in use for the Merkava that I am modeling. Model Miniatures comes to the rescue with their cast resin wheel sets, so I placed an order via the Internet and had my hands on a set in less than a weeks time! The single piece cast resin road wheels are an exact match to the two-piece moled plastic Revell road wheels.
The kit idler wheels took me the longest to modify. With a needle fixed to a pin vise I dimpled all 80 holes at 20 per wheel and then attached a micro drill to a Dremel rotary tool and carefully drilled out each of the holes as on the real Merkava idlers. I then fixed the idlers to the Dremel rotary tool and using a course grit sanding stick I brought down the wheels thick dimension closer to scale thickness and polished the surface with a medium grit sanding stick followed by an old worn out toothbrush ala Alex Clark's Small-Scale Armour Modelling book. The center hub caps where then drilled out and replaced with a more to scale solid styrene diameter rod. The rod ends where shaped on the Dremel rotary tool with the medium sanding stick prior to inserting them into the idlers.
Wheel Alignment
When I test fitted all of the wheels on the lower chassis I found that the Revell and Model Miniatures road wheels where not in alignment with both the drive and idler wheels so a little modification was in order to have the road wheels line up with the drive and idler wheels. The supplied kit link and length tracks don’t have track guide horns or for that matter any detail molded onto the road wheel contact surfaces making it easy work to fit them around all of the wheels regardless of the misalignment between the drive and idler wheels and the Revell and Model Miniatures road wheels. But because I will be adding guide horns to the tracks it was imperative to have all of the running gear wheels line up. Let’s take a look at what was done to resolve this issue.

Using a sub-miniature punch and die set I fabricated disks to place the road wheels further away from the suspension arms and to center them with both the drive and idler wheels. I also used the punch and die set to fabricate bolt heads for the idler housings and replaced the molded on idler adjusting hardware with cast resin items. Solid styrene rod and the same diameter brass tube were used to replace the molded on gear drive housing shafts and track support wheel axle shafts respectively. As mentioned above I had also drilled out the gear drive housing attachment bolts on both sides of the lower glacis plate.

The reason for replacing the molded on gear drive housing shafts (inset photograph) with solid styrene rod replacements was because I moved the drive wheels a little further forward to shorten the distance from the end of the front fenders as per photographs in my reference books and also written material, photographs and coffee sent to me from fellow modeler and IDF enthusiast Joel Gewirtz over at Missing-Lynx, thanks Joel, it is very much appreciated. We’ll coffee together one of these days!

In this view you can clearly see the difference it made by relocating the drive wheel housing shafts just a bit forward. This will also allow the tracks some room away from the drive housings as per photographs of the real deal.

The now aligned running gear with the replacement Revell and Model Miniatures road wheels. From this view you are able to see how much closer the drive wheels now are to the front edge of the fenders.

Here you can see that the track support wheels are now centered over the road wheels. The original molded-on support wheel shafts where much to short in length and did not allow for any adjustment in placing these wheels correctly over the road wheels. I used Pedro Andrada’s method for cutting a groove into the kit supplied support wheels; these are cast as a solid single wheel. I’ve also added the Bazooka support brackets, these where usually removed when the Bazooka shields where not on the vehicle to prevent them from becoming bent and jamming themselves up against the road wheels.

The suspension detail in this old kit is very detailed and accurate.
Adding the Track Guide Horns

1) With a square ruler and Squadron’s scribing tool a series of grooves were made across the width of the road wheel side of the track link face. Each of the scribed lines is started between the V shaped portions of the track links outside edge. A faint scribed line was made down the center of the length of the track links to be used as a guide in placing each of the track guide horns.
2) A medium grit sanding stick was used to remove and smooth the raised plastic left by the scribing tool. A gentle scrubbing with a small piece of Scotch-Brite followed this.
3) The track guide horns were made from .015” T X .040” W (0.381 mm X 1.016 mm) styrene strip cut to a length of .043” (1.092 mm) long. Held length wise with a pair of flat nosed tweezers one end of each of the track guide horns were dipped in liquid cement, that had been placed in a metal tin, and carefully placed on the scribed center line of each track link. The liquid cement evaporates quickly so you’ll need to keep adding more cement to the tin as you work, I used a No. 2 paint brush for this task.
4) When eight track guide horns had been placed on the track links a set of calibers were use to align them before proceeding with another set of eight until all of the track links had a track guide horn fitted to each of them. The tip for the technique on using a set of calibers to align the track guide horns with the track links comes from Alex Clark’s book ‘Small-Scale Armour Modeling’ as does the inspiration for even attempting to add the guide horns to the track links in the first place, he makes it look so easy and as I found out while going through the process of doing the same for these tracks, it is!

5) To assure that the spacing between each of the track guide horns was at least correct I inverted a section of track links and placed the open cutouts for the drive wheel sprocket teeth over the guide horns to make any necessary adjustments before the cement has time to cure.
6) When I was satisfied that the guide horns were evenly spaced I applied Tamiya’s Extra Thin liquid cement between the guide horns and track links on each side of the guide horns. The cement was allowed to cure overnight before proceeding with the next steps.
7) Using a triangular jewelers file I slightly beveled the top corners of each of the guide horns.
8) A medium grit sanding stick was used to knock down and smooth out the fuzzy bunnies left on the guide horns from filing.

9) To round off and create a slight bevel nearest the top edge of the guide horns on the side surfaces I used the same medium grit sanding stick but slightly angled the sanding stick as I sanded.
10) Finally a gentle scrubbing with Scotch-Brite to polish and smooth out the top corner edges of the guide horns.
Several sections of track links, those running along the top, did not receive guide horns, as they would not be seen once the bazooka shields are fitted. Only a partial amount of guide horns were place on one of the top track link sections as I have planned on leaving one of the bazooka shields off the model.

The single shield that won’t be getting fixed to the model is the right rear bazooka shield so I placed the top section of track links with the guide horns on that side (indicated with red arrow). I also did not place two of the separate individual track links on either of the drive wheels (circled in red). This will not be noticed once the mudguards are in place with the bazooka shields. The kit only includes enough individual track links to complete the track runs with two pieces left over for use on the turret sides. I would like to model this vehicle with two spare track links up front on the lower glacis plate and two track links on each side of the turret base, so without having to go and cast these links I now have the quantity that I will need. Hihi!
Track sag on the Merkava is very minimal to non-existent on these vehicles, at least from the photographs that I have seen, but I wanted to add a small degree of track sag to the vehicle that I’m attempting to model here so I think that a slightly warn look from use during the hard fought armored battles of the Lebanon campaign would not be out of place. Although once the bazooka plates are fitted, with the exception of the right rear plate, you’ll not be able to notice this feature anyway.

This is as far as I have gotten on the project to date. But I’m happy with the results and can now move on to the upper hull.
Feedback and comments are welcome, thanks for stopping by,
