Garage remodel – Building a new work bench part 1

I’ve been working with a smallish work bench in the garage for some time now and it’s time to build a bigger one. I have a large one in the “hack shack” that I built several years ago (hack #2 back when I was counting) and I’m using a similar build plan for this one. The main difference is in the legs which will be made from 2″ x 4″ lumber. This bench will be getting some pretty heavy duty use so I’ll be reinforcing it with some extra wood underneath.

It’s all explained in this weeks video.

Railroad spike in the face for Halloween.

I’ve worked around some theater folks in the past and I picked up on a few simple makeup tricks using liquid latex. Liquid latex can be brushed onto the skin and built up to create a variety of effects, one of which is torn skin that looks like a wound. By adding latex to tissue paper you can create some pretty amazing looking wounds, scars, zombie faces etc.

This week I’ll show you the basic technique of creating a wound on my face, with a fake railroad spike poking in and out of it.

1973 Honda CB750 Custom Build Episode 12

The camshaft chain and the primary drive chains in the CB750 engine can wear and stretch. When rebuilding one of these engines, it’s important to inspect these items to determine if they need replacement. In this week’s video I’ll show you how to inspect both of these items. I’ll also share a technique to determine which bolts go where when putting one of these engines back together.

1973 Honda CB750 Custom Build Episode 11

This week I notched the cylinder skirts so that the forged aluminum rods can clear them during rotation of the crankshaft. I used a Bridgeport milling machine and a radiused end mill to do the job. I followed up with a small grinding stone on a Dremel too to chamfer the notch and eliminate any rough edges that might harm the piston.

The depth of the notch ended up being 8 mm with a width of 28 mm. This allowed the forged aluminum connecting rods to clear the cylinder skirt by a little over 2 mm.

EICO Model 147A Signal Tracer

I found this signal tracer at an antique festival here in North Carolina. The festival is a yearly event and there always someone there with some vintage electronics. As I was walking around the event this piece caught my attention. The seller wanted $20 for it, I offered $15 and we struck a deal. It’s in great condition and it still works quite well.

EICO (Electronic Instrument Corporation) was established in New York City in 1945 by radio repair business owner Harry Ashley to manufacture electronic test equipment in kit form. Their first product was an audible signal tracer.

In my research on this piece I found some good info.
