I.D. this radio mount.

Post by clintm20 » Wed Jul 22, 2009 10:28 am

Left hand side of the pictures shows a partially visible radio mount.

This is mounted in a halftrack and I have one like it. Does anyone know the nomeclature for it? I've only seen them in halftracks but would imagine it was used in other applications. I believe an FT-237 mounts to it but not sure about that either.

Clint, that is the FT-284 and it is very specific to SOME of the half tracks. There is a chest that fits on top of the short table, the CH 76 I think it's called. I think it only goes in the the M3 and/or M3A1 model half track, but I may be wrong about the model number of the half track. I make reproductions of this mount, and have several on hand.

Tom,

Thank you very much. I was up at the museum in Huntsville last weekend and Ralph mentioned you were making these.

I was hoping you would see this thread.

Best Regards,

Clint

Brian,

I don't think that there are any slots in the rear legs. The straight strip that runs across from left to right is part of the bed of the half-track. There would be no purpose to slots in the bottoms of the legs since the FT-284 Mount is welded in.

Also, from an earlier couple of posts, the chest that sits on top of the FT-284 is the CH-74.

in the bottom corner is a piece of 1 1/2 inch angle iron that runs the length of the bed and holds the sides of the the halftrack to the "floor/fender"
the back legs sit on top of this angle iron. the armor is bolted through every 8 inches. of course the bottom bolts are offset from the side bolts.

the slots are for the nut side of the side bolts to stick through

if you click on the pic it will blow up

heres the other pic, and manual plans

note the extra little foot pad, to shim the back corner leg to the level of the angle iron.

I blew up this pic and outlined on paint and can send it to you

I think the titty to titty distance on a 3/8 nut is .491, so that would give you 1/2 inch slot to clear.

next question is- ( and I couldent stand on my head good enough to get a measure)

are the side bolts centered on the ID, or the OD of the angle iron, (which is 1/8 inch thick.)

I think my non engineer self would have centered them on the ID, in order to gain socket clearance, but what do i know.

Brian,

OK. I thought something like that would be the case. Yes, please send me the blowups.

In the photos down this thread and the additional photo, the FT-284 construction matches the sketches that I got from Jesse Browning years ago. But in November of 2007 someone sent me photos of a half track with an SCR-528 in the right rear corner and a TCS in the left rear. In both of those photos, the angle iron across the front is installed with the vertical leg to the front straight under the front edge of the bottom of the CH-74. Yet the three front legs are still set back from the front edge about the same amount. My first guess is that the front cross member is channel instead of angle. It does make a better looking mount. I have no recollection as to who sent the photos or whether they are original or restoration. But I would assume the latter as the FT-237 DC cord runs out the front of the mount instead of out the right end of the CH-74, And the TCS transmitter and receiver power cables look like they are standard shipboard lengths - much too long.

I should also point out the reason for the slots, is because you cant get to the side bolts, from the outside due to the mine racks.
