I need to make a wrench to snug down the wing nuts on my recently converted Sharpe pressure pot. The ears are not tall enough to use a screwdriver or similar. Any ideas or pictures to help me out?

G'day, I have shown here in one of my games (not sure which one) where I asked to identify the item in the pic and that was a wooden handle I made very roughly to assist me to tighten the pressure pot wing nut bolts.
As other mentioned, a grove cut in the piece of wood to fit over the wing nuts (partially) and about 7" long is all you need, the longer it is the more torque you will put into those bolts.
One thing that you need to consider is to buy another seal for that pot, they are on sale on eBay, at that age, the rubber would had lost its flexibility and therefore making it much harder to seal.
Another important detail is to lubricate the seal and pot faces that will be in contact, vaseline is good, I use a Leather lube preservative gel that I had and tested to see if it would react with the rubber, it didn't so I use the smaller brush used to apply it over the boots to quickly lubricate so slightly the contact surfaces and that will seal the pot using much less torque.
After I used this tool, I decided that I needed something faster to tighten and loosen those nuts, I was smart enough to use a screw gun I had (Hilty) that had a good clutch for the torque, I adjusted it so that it would stop spinning at a certain torque level to prevent to overtighten of those bolts and therefore damaging them.
It all worked good until that screw gun died on me after 15 years of use, I requested a quote for repair and I would cost more that buy a new screw gun of a less expensive brand than Hilty.
I did not buy a new screw gun for a while and decided to use an old wrench socket and an extension rod, cut a groove into the middle of the socket and with the use of a wrench like the one of James, I got the tool made and working however, not as fast as the screwdriver gun, I started to notice that I was overtighten the bolts far too much, using the wrench is not easy to control the torque so and in not time, I had the bolts and housing damaged to which I had to tap a bigger size thread, enough to clean the old thread and not weaken the housing too much, I then matched some bolts with the thread needed, cut the heads and replaced them with the wing nuts from the older bolts, put some Teflon grease on the threads and everything is working back to almost new.
I now have another screwdriver gun for this purpose, again...!:biggrin:
I hope this helps...!
